Well the "processes" page of the gnome-system-monitor application seems to show very faulty data. The diskread total and diskwrite total for any application is "N/A" (even though I know certain applications save to disk, and I am trying to debug this, since disk seems to constantly run & seem to lag down the whole system).

On top of that the actual cpu usage is always "0" for any application, yet in the "resources" tab I see total cpu be somewhere around 20-40%.

What is causing these problems and how can I fix it to find which process is keeping my hard drive busy?


On request here is a log of the system monitor while webstorm is loading (and I actually hear the hard drive being busy, and cpu is also not zero). The process marked (java) is what corresponds to webstorm ide: which is actively loading.
I'm using ubuntu 18.04

  • Hey, would you mind posting a screenshot? It may be just my version of the sys monitor, but I don't have anything that looks like diskread or diskwrite. Also, what types of processes are you showing (yours, active, or all?) Furthermore, what kind of specs do you have on your system? – anonymous2 Feb 28 at 1:00
  • @anonymous2 Just added the picture, as shown it only shows my processes – paul23 Feb 28 at 13:43

    @N0rbert what does that have anything to do with the inner workings? And the inability to check other applications? – paul23 Feb 28 at 21:13

    @N0rbert how can I see this? The system monitor is just installed as per default in my system, so I guess with 18.04 it is snap. However that doesn't solve the problem, the question linked is asking why it is installed as snap. It shouldn't misbehave since it's a default application? So there must be something else wrong. – paul23 Feb 28 at 21:21
  • Have you tried clicking on the %CPU column so that it sorts by CPU usage? The most CPU usage will appear at the top of the list. The way that pic shows, it has it listing the lowest at the top. – Terrance Feb 28 at 21:56
